Download BEST Console Calculator
Harold Guildford
Console Calculator is a powerful calculator with a simple console interface. This calculator includes many built-in mathematical functions, remembers recent entries, and supports creation of user defined variables and custom functions. Includes features that programmers or engineers will love, such as a built-in unit converter, SI-unit prefixes (u = micro, m = milli, etc) , and support for binary and hexadecimal. The interface is simple, fast, and elegant.
Awesome tool. For years I have been torn between using the crappy windows calculator or firing-up an instance of Matlab for my calculation needs. CCalc fills the gap: high level math functions with a down-to-earth console window.

In this tutorial, you use Visual Studio to create and run a C# console app, and explore some features of the Visual Studio integrated development environment (IDE). This tutorial is part 1 of a two-part tutorial series.
The default "Hello World" code calls the WriteLine method to display the literal string "Hello, World!" in the console window. If you press F5, you can run the default program in Debug mode. After the application runs in the debugger, the console window stays open. Press any key to close the console window.
The single code statement calls the WriteLine method to display the literal string "Hello, World!" in the console window. If you press F5, you can run the default program in Debug mode. After the application runs in the debugger, the console window stays open. Press any key to close the console window.
You improved your basic calculator app, but your app doesn't yet handle exceptions, such as user input errors. For example, if users try to divide by zero, or enter an unexpected character, the app might stop working, return an error, or return an unexpected non-numeric result.
You can now run more calculations until you choose to close the console app. There are also fewer decimal places in the results. And if you enter an incorrect character, you get an appropriate error response.
The usual starting point for a C++ programmer is a "Hello, world!" application that runs on the command line. That's what you create first in Visual Studio in this article, and then we move on to something more challenging: a calculator app.
An empty C++ Windows console application gets created. Console applications use a Windows console window to display output and accept user input. In Visual Studio, an editor window opens and shows the generated code:
A console window opens and then runs your app. When you start a console app in Visual Studio, it runs your code, then prints "Press any key to close this window . . ." to give you a chance to see the output. Congratulations! You've created your first "Hello, world!" console app in Visual Studio!
To run the application, press Ctrl+F5 or go to the Debug menu and choose Start Without Debugging. You should see a console window appear that displays the text specified in the code.
Since the user is free to type anything into the console window, let's make sure the calculator handles some input as expected. Instead of running the program, let's debug it instead, so we can inspect what it's doing in detail, step-by-step.
To debug the program, press F5, or choose the Local Windows Debugger toolbar button that has the green arrow icon. In your console app, if you enter something like "5 - 0", the program behaves normally and keeps running. However, if you type "10 / 0", it pauses at the breakpoint. You can even put any number of spaces between the operator and numbers: cin is smart enough to parse the input appropriately.
It looks like the program is doing what is expected: it takes the first number, and divides it by the second. On the cout line, hover over the result variable or take a look at result in the Autos window. Its value inf, which doesn't look right, so let's fix it. The cout line just outputs whatever value is stored in result, so when you step one more line forward using F10, the console window displays:

To run the application, press Ctrl+F5 or go to the Debug menu and choose Start Without Debugging. If you get a pop-up that says This project is out of date, you may select Do not show this dialog again, and then choose Yes to build your application. You should see a console window appear that displays the text specified in the code.
Short video showing Debug > Start without debugging. A dialog is visible that asks whether to build because the project is out of date. The checkbox for 'Do not show this dialog again' is selected. 'Yes' is selected to build the project, the calculator project builds, and then launches in a Windows console window.

The BSM ICS Driver should be installed on the Citrix Server along with all the other Drivers and ICSs they use , so the calculator should be installed by default . They could check add remove programs to be sure.
The Calculator.exe ( or whatever the name ) would need to be published as an application in their "farm" just as the Empower.exe is done . Once this is published the Citrix ICA clients should have access to use the calculator.
I was asked how I might go about automating an online calculator application. I have a calculator app of my own so I was interested in comparing the two apps and experimenting with a canvas based JS App.
But neither of those seem to launch, so how do I launch the calculator through Terminal? What command do I use? Also, as my Unity Dock is rather full, it's not really an option just to put a link to it there.
Console Calculator is a calculator with built-in console interface. You can enter complex expressions and see the results of multiple expressions at the same time. Console Calculator includes many built-in mathematical functions, remembers recent entries, and supports creation of user defined variables and custom functions. Also available for Mac OS X.

You have just executed your first R command! The top left portion is the script. This is a placeholder for the various commands. When you want to run a command, RStudio will send it down to the console and execute it.
As a final, slightly borderline remark, let's note that bc is not just a calculator but rather a full-fledged programming language (including user defined functions, while & for loops, etc etc). Another fact that suggests to prefer the build-in arithmetic capabilities for such simple calculations, rather than an external program. That said, extracting the data for given partition number(s) and dealing with "M", "G" suffixes, as the original question seemed to ask for, might call for (g)awk rather than bc.
Description: console calculator concalc is a calculator for the Linux console. It is just the parser-algorithm of extcalc packed into a simple console program. You can use it if you need a calculator in your shell. concalc is also able to run scripts written in a C-like programming language.
(The original issue has been solved multiple times already. However, the title "Simple command-line calculator" may require division to some decimal points. The use of the -l option with bc seems to give 20 decimal points, which is perhaps too many for a 'simple' calculator. This answer, which frankensteins answers from @stephenKitt and @sjas was the simplest solution I found.)
There are a lot of great answers here, I actually have written a small programming language with this problem in mind, where in typing in the command line./Ascal 2+2or./Ascal "log(10)"you will immediately get the resultFinal Answer:4for 2+2, and I'm sure you can imagine for log base 10 of 10.Just something to keep in mind, it's also a full programming language with a bunch of useful functions built in, plotting in the console, and taking reimann sums of functions you have defined.Check it out the project now comes with a build script so all you need to do is add it to your path variable, or add an alias in your bash config and you have an easy to use calculator!
I'd also be really appreciative of any comments anyone interested enough to check it out might have, hope it can be useful.
